From fe35a40e675473eb65f2f5462b82770f324b5689 Mon Sep 17 00:00:00 2001 From: Varun Prakash Date: Sat, 12 Jan 2019 22:14:30 +0530 Subject: scsi: csiostor: fix NULL pointer dereference in csio_vport_set_state() Assign fc_vport to ln->fc_vport before calling csio_fcoe_alloc_vnp() to avoid a NULL pointer dereference in csio_vport_set_state(). ln->fc_vport is dereferenced in csio_vport_set_state().
